On Intel Mac OS X or PPC Mac OS X ?

For Intel you need a set of patches that was posted here a while ago, see:
     http://gcc.gnu.org/ml/java/2006-05/msg00151.html
I don't know if these patches have been checked in anywhere yet.

For PPC Mac OS X, you should just be able to run configure as usual. Here is 
how I do it:

../gcc-3.4.4/configure --enable-threads=posix \
                        --prefix=/usr/local/gcc-3.4.4 \
                        --enable-languages=c,c++,java

On PPC Mac OS X, I wasn't able to build gcj 4.x yet directly. But I got gcj 
4.1.1 to build via darwinports.

I hope this helps...
